Pump |24 is preferably two pumps in one casing. These two pumps, or pumpsections, will be designated by the numerals 200 and 202. Preferably,one of these pumps will be bigger than the other.

Operation A web roll Winder made according to this invention willgenerally be used in a train with a number of cars adapted to carry aplurality of rolls. In the application of the invention envisaged by theapplicant, the web rolls handled by the invention are belt rolls, forexample the belting that is used in belt conveyors.

A train goes to a belt conveyor location including in its train a beltwinder made according to this invention and one or more belt carriercars. When the location for a conveyor is reached, a roll of belting isremoved from the carrier car to the belt Winder. This is done by turningthe base on its vertical axis until it is oriented in such a manner thata roll of belting may be easily rolled onto the transport |26. The rollof belting is of course rolled into place with the core |06 `and spindle|04 removed from the bearings 86 and 88.

The transport is then raised in order to bring the belt center above thebearings 86 and 88. Raising ofthe belt is accomplished by admitting duidunder pressure to the left end o1' hydraulic jack |12 as seen in movedto the right, the pulley |66, thus rotating n vertically by v1rtue ofthe guides |38 and guide blocks |40. When the belt roll has been raisedas high as necessary,

conveyor. The belt is then ready to be unbanded and to be unrolled ontothe conveyor as will be well understood by those skilled in the art.

Let it now be assumed that a section of belting is to be remo-ved from abelt conveyor. A belt Winder according to this invention is pulled to astop as close to the conveyor as is possible and the base is swivelledon its vertical axis until it is alined with the belt line of theconveyor. The belt on the conveyor is unhooked by breaking the belt at alacing, and the upper run end of the belt is connected to the core |06.The connection is'made by passing one or the other of the pins or rods|08, ||0 through the depending on the size of the belt lacing. The bewound onto the core |06.

connected as aforesaid, power is applied to the hydraulic motor |20. Itwill be understood by those skilled `in the art that, at the outset, theradius about which the belt winds is relatively small, and a relativelyhigh torque is available with only one of the pump sections 200, 202.Accordingly, the pump section which is not to be used will merelyby-pass oil through its control valve.

Let it be assumed that pump section 202 suilices at thestart to wind upthe belt and drag the tail piece. In that case, pump section 200 willsimply by-pass oil through its control valve 204, `and pump section 202will pump oil under pressure to theV hydraulic motor by way of conduit2|0, through control valve 206, conduits 224 and 222, control valve 220,and conduit 234. Fluid returns from the hydraulic motor by way ofconduits 236, 228, and 2|2, reservoir 2| 4, and conduit 2|8 back to thepump intake. As the belt piles up on the core, the radius of the beltroll increases to the point Where the pump 202 cannot supply thenecessary torque. If then pump 200 Vupon both pump sections 200 and todrive the hydraulic motor.

It will be obvious to 'those skilled in the art `that flexible tensionmembers |48 and |66 can- `not transmit compressive forces. In otherwords, the transport |26 will have to move downward by the influence ofgravity." Nevertheless, the

hydraulic jack I12-is preferablymade a doubleacting jack in order thatthe piston vrod 114 may be powered leftward as `seen in Fig. 8. Thismakes it possible to eliminate sticking of the jack and does not limitthe operator to the force of gravity in moving the jackv parts to effectlowering of the transport |26.

A web roll winder made `according to this `invention provides means forhandling heavy belt rolls completely by power, .thusobviatingthetedious, awkward, and often dangerous handling .of heavy rolls ofbelting underground where` maneuvering space is often very limited. Abelt Winder made according to this inventionoperates with very low headroom and is exceedingly flexible in its application. Other advantageswill be apparent to those skilled in the art.

While there is in this application specifically describedone form whichnthe .invention may assumeY in practice, it will -be understood thatthis `form of the same is shown for purposes of illustration, and thatthe invention may be modilied and embodied in various other formswithout departing from its spirit or the scope of the appended claims.
